J Mehra and H Rechenberg 1982 Berlin: Springer Part 1 xlvii + 372 pp price DM75 ISBN 3 540 90642 8, Part 2 vi + 878 pp price DM85 ISBN 3 540 90667 3 These two volumes, which are the first of a massive ten-part enterprise, provide an exhaustive treatment of the foundation of quantum theory by Planck, Einstein, Bohr and Sommerfeld and the advent of its difficulties in the first quarter of the 20th century. The chief aim of the authors was to use the written resources and the recollections of leading physicists to describe the main ideas of and events in the birth of quantum theory.

Arrival of the New Quantum Theory

David K. Ferry

The concept of eigenvalues comes from linear algebra rather than quantum mechanics, and came into the latter through the use of linear algebra and matrices. Arnold Sommerfeld felt that Niels Bohr’s atom could only be approximately correct in that it really had only one quantum condition, other than the use of Planck’s model. Paul Dirac had made significant advances in the foundations of quantum mechanics, and particularly in the mathematical basis of the theory, while the Gottingen group was waiting for their paper to appear in print. “In the present theory, the fundamental principles of quantum theory and the principle of conservation of energy follow mathematically from the quantum-mechanical equations.” Paul Ehrenfest was determined to try to calm the water between Bohr and A. Einstein. The rise of the new quantum mechanics had only served to stir up the debate once again, but Ehrenfest would not give up the task.
